Specification of Letters Patent.

Patented June 10, 1919.

Application filed March 14, 1918. Serial No. 222,342. i

To all whom it may concern:

Be it known that I, WALTER J. PUTNAM,

a citizen of the United States, and a resi tire the tire armor forming the subject mat-' ter of my prior Patent No. 1,187 ,173, dated June 13, 1916.

In the drawin s:

Figure l is a slde view ofa ortion of the tire armor in place, showing t e connecting means for the holding cables;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a for the nut;

Fig. 4 is a section on Fig. 1;

Fig. 5 is a perspective view of another embodiment of the invention, with the cables broken away;

Fig. 6 is a plan view of the plate.

The present embodiment of the invent on is shown in connection with a pneumatlc tire 1 of usual construction seated upon the usual telly 2, and arranged to connect the ends of a cable 3, which is provided for holding upon the tire the armor 4: formlng the subject matter of my prior Patents Nos. 1,187,173 granted June 13, 1916, and 1,259,77 6, granted March 19, 1918. o

This armor, as shown, consists of units which are'connected by links, and is provided at its opposite sides with double hooks 5, which are connected with the cable 3, and the holding plate 6 which is a base for the mechanism for connecting the ends of the cable. This base, as shown, is of trapezpt dal form, and is arranged with its long side perspective view of the lock the line i -4 of adjacent to the tire armor and with its short side adjacent to the rim. This plate has openings 7 near the ends of 1ts long side, which are adaptedfor engagement y the bills of the double hooks 5 which areadjacent to the plate, it being understood that the remaining hooks of the tire armor at that side (it the wheel engage the cable d1- ftiiitly. j

This plate 6 has extending laterally therefrom at approximately the center a stem 7 rigidly connected with the plate, the outer end of the stem being threaded for engagement by a nut 8. The plate also has at the opposite sides of the stem slots 9 which are adapted to receive the sides 10 of a keeper, the said keeper consisting of the sides 10 and a body 11. The ends of the cable 3 are adapted to be bent about the stem 7, that is, doubled upon themselves, as shown more particularly in Fig. 1, and each free end of the cable is connected to the body of the cable by the mechanism shown in Fig. 4.

The said mechanism comprises a screw bolt 12 whose head is received in a counterbored opening in a keeper consisting of a body portion 13 and arms 14. The arms extend at an acute angle with respect to the body. The body of the cable 3 and the end are engaged between the side walls 14 of the keeper and the bolt 12, and a nut 15 is threaded on to the bolt.. These arms 14.- of the keeper are bent sufliciently far inward and the nut is of such diameter that the cable cannot escape from between the nut and the arm, and the cable is thus clasped tightly to the keeper by the nut.

It will be noticed that the edges of the nut adjacent the cable are beveled to facilitate the arranging of the nut on the bolt. The

loops formed at the ends of the cable in this manner are passed over the stem 7, after which the keeper is placed over the loops as shown in Figs. 1 and 2, and the nut 8 is threaded on to the same outside the body of the keeper. The keeper is thus clamped on the loops which are forced down tightly against the plate in such manner that there is no possibility of their displacement.

Preferably, the nut is locked by the lock shown in Fig. 3. This lock consists of a plate 16 having an opening 17 fitting the nut and engaging the same, the plate resting upon the body of the keeper. The plate has a portion 18 which is offset laterally with respect to the portion 16 into engagement with. the plate 6, as shown in Fig. 2, and the plate and the lock have registering openings for receiving a hook 19 to hold the lock to the plate. This hook, as shown, has an eye a link 21, and the passed through'the'bill of the hook 19 to se--' cure againstaccidentahdisplacement of the parts.

In use, the ends of thecable have loopsas specified, and they are fitted over the stem 7 after the armor has been placed nponithe 's' Wheel, and it will be noticed that openings 23 areprovided in the plateG near its ends for engagement by a toolto facilitate the placing 'of the parts. After' the-*ends-liave" been looped over the stem, the keeper 1011 is placed andthe nut "8is screwednp tight", after-Which the lock-is placed and the hooks 19 are "engaged with the locks" at opposite sides o-f the-Wheel. The link 21 extends between the spokesacross theu'infand in addition-to this function of holdingthe locks in place-"prevents movement-of the armor cir- I cunifernti ally of the wheel:
